Quadcopter Dive Brakes

this is a prototype working only on the bench so far it is a frame designed to cable tie to the bottom of a x frame freestyle quadcopter the flaps are to fit with servo pushrod wire to allow free movement these flaps are then activated by micro electomagnetic pistons activated by a tilt switch to active upside down all powered by a balance lead connector this design will need someone to develop it to work fully enjoy and i look forward to seeing the first pilot vid of it on youtube
